Another way of saying "whatever". It is often confused with "same thing", but you're really saying "OK, I admit that they're not the same thing, but they're not different enough for me to really care about it."

The saying or phrase with these specific two words that contradict each other for a common goal of agreeing with someone when they prove you wrong but still keeping the appearance that you are right too. Also somehow in the process that even though they were right that they in some way are retarted for calling you out.
